Hoping that someone can help me with this - I have spent all day trying to sort it!
In short - I have two screens, at two different resolutions. (Viewsonic VA2431w @ 1920x1080 and HP ZR270w @ 2560x1440). I have attempted to set them up as two twinview screens, using nvidea-settings under nvidia driver version 304.48 on a GeForce 8400GS.
The problem is that only one screen (the Viewsonic) displays anything. The other (HP) is blank with a black screen. It flickers on a X-restart, as though it were expecting signal, but nothing appears.
xrandr shows that the graphics card picks up everything as it should (below)
My xorg.conf follows ...
I would be SO grateful for any help clearing this up!
